E.T. Talk

Will it be possible to communicate with intelligent extraterrestrial life forms if we find them? How could we establish this communication, where would we begin? What does it mean to say that mathematics is a universal language? How could math be used to communicate with ETs? This book summarizes the work of SETI, the Search for Extraterrestrial Intelligence, and other search programs and considers the implications of, and concerns about, their possible success. Surely the next step after finding life elsewhere would be to try to communicate with it. The author of this book will suggest concrete ways to approach this problem.
